While driving, my vehicle suddenly shut off without warning. After restarting, the vehicle would not accelerate over 40 miles per hour. I had the vehicle inspected by the dealership, and they informed me that the engine oil filter contained metal debris. The dealership explained that the presence of metallic particles in the filter could indicate internal engine wear or damage, and they recommended a full engine replacement at a cost of approximately $20,000. At this time, I have not been shown the filter or the debris, but I was advised that this condition may require further diagnosis and possible engine repair or replacement.

STEERING,SUSPENSION
1 complaint
This car has been drifting to the right since bought causing premature tire wear which has now been 5 sets of tires in 36k miles. The front right tire always seems to blow out. Alignment has always been knocked out in within weeks. Several independent shops point to defective bushings while infiniti doesn't see the issue. This same issue was recalled for the 2016 models. I've replaced the knuckle and lower control arm and now stays aligned but seems to causing premature tire wear and blowing the right front tire. I cant get more than 10k miles out of a set of tires and constant fighting with the car drifting to the right. I have several more documents. The consumer stated the reason for the drifting, the tire tears, and alignment knocking was due to a defective rack and pinion. The consumer stated that the dealerships are refusing to replace the defective part on the vehicle under the warranty that is now expired. Paying for alignments and tire replacements is a waste of money considering the root of the issue has not been fixed yet. The consumer stated that due to the multiple issues, they will not be able to do a private sell of the vehicle. The only option would be to sell it to the dealer.

SEATS
1 complaint
Passenger front seat shakes/vibrates even at lower speeds and it makes lots of noise. Tires were checked and has nothing to do with tires. I actually googled issue on my model and there are tons of posts with this exact issue. I have an appointment for dealership to look at issue in the next couple of weeks. My concern is that other consumers who have had issue that I’ve read about online had not had the problem rendered. It was not considered part of warranty. I’m my opinion, it should because it’s an obvious defect. I should not have to pay out of pocket to have this corrected if it’s defective.

I have 3 issues with the car. The braking issue presented itself last in time but is most important relative to safety. Around mid January 2022, my car, while I was driving, and without any notice, began to decelerate/brake for no reason. My car is equipped with front driver assist but there were no cars, hazards, in front of me. It was a clear, dry day and the car was warm. It was momentary and fortunately no one was behind me. The car beeped, but there was no other warning. The second time this same event happened, however, the accelerator pushed back against my foot. Again, no one was in front of me and it was a clear, dry day. The third time this happened, the car beeped and what I know now is the cruise control indicator, appeared on the display. I did not touch the cruise control to activate. The other two issues were that both display screens were blacking out and rebooting while driving, for no apparent reason. The other issue is with the Sirius XM satellite, which is not functioning properly. I have informed Sirius XM of this issue as well. Given all of these issues, possibly all electrical, I contacted my local Infiniti dealer to assess, with special concern for the random braking issue. The car was assessed and they could not duplicate any problems. They mentioned that perhaps if they had more time they may be able to duplicate the problems. The following Monday, I took the car to the dealership and left it overnight for assessment. I was called the next day and advised that they could not duplicate the issues. The dealership returned the car without making any repairs, diagnoses, or being to able to duplicate problems. Since the car has been returned to me, it has continued to have problems. The braking issue has happened twice since, with one time involving the accelerator pushing back. The screen has blacked out and gone into parking mode, while I was driving. I have contacted Infiniti corporate to advise of problems.

While vehicle is in “D” drive move the car would jerk likes its trying to shift/switch gears and jerk hard. It sounds like the issue would involve the transmission. Another occasion happened when I came to a complete stop, & then pressed on the gas, and the car jerks again then started to accelerate.

The car sometimes turning - changing lanes - just various times the rear end will slide around - or skid. Just does it various times - does not matter if the road is wet or not. Infiniti Service did not find an issue - but there is definitely an issue. No certain time so hard to pinpoint what is causing it.

I ORIGINALLY OWNED THIS Q50 2018 VIN [XXX] AND INFINITI REPLACED IT WITH THE ONE I HAD LISTED. THE FACT IS I OWN NEITHER OF THEM ANY LONGER BUT FEELI SHOULD REPORT IT BECAUSE IT IS A SAFETY ISSUE WHICH INFINITI REFUSED TO DEAL WITH. THE BLIND SPOT LIGHT DID NOT WORK ON EITHER CAR . BETWEEN 10 AM AND 8 PM YOU COULD NOT SEE THE LIGHT AND AUDIBLE SIGNAL YOU COULD BARELY HEAR. I AM REPORTING THIS PROBLEM IN THE HOPES OF SAVING LIVES. IT WAS A SAFETY ISSUE IT COST ME $$ THE SECOND REPLACEMENT BUT NEVER FELT COMFORTABLE IN THE CAR . YET INFINITI COULD CARE LESS THOUGH THE DEALER WAS VERY HELPFUL INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TT *TR
